DIPROVELEENT IN COOKING-S'1'OVES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it mag concern p 'Be it known that I, ROBERT HAM, of Troy,in the county of Rensselaer, and State of New York, have invented anImproved Hot-Water Reservoir for Cooking-Stoves; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, making part of this'speciiication Figure 1 being a top view of the reservoir, the coverbeing removed.

Figure 2, a back view thereof.

Figure 3, a bottom view of the same.

Figure 4, a transverse central vertical section of the reservoir, inconnection with the back part of a cooking-stove, showing the mode ofconnecting it with the stove or range.

Like letters designate corresponding parts in all of the figures.

The reservoir A is located at the back of the stove, and preteiably, hasa step, or projection, a, reaching forward a short distance, so as torest on the top, D, of the stove, to which it may be attached, byscrews, or otherwise. 7 v

A portion of the reservoir may reach above the stove, as shown in thedrawings, or its topmay be brought nearly down'to a level with thestove.

My invention consists, first, informing a flue, B, by indentation intoboth the bottom and back of the reservoir, so as to receive the draughtthrough an aperture, f, in the back of the stove, and transmit it alongthe bottom and back of the reservoir, exposing along its whole extent,all its surface, except the plane, or nearly plane, outside surface, orwhat is equivalent to three sides of the fine, to the water in thereservoir,

an unusual amount of heating-surface.

A collar, cl, at the upper end of the flue, receives the smoke-pipe ofthe stove.

Practically the reservoir is made of cast iron; and

another feature of my invention consists in casting the whole body ofthe reservoir and all of the inside plate 12, of the flue, in one piece,whereby extreme economy of construction is secured, and no joint, liableto open and leak, is exposed to the water.

The fine-plate b is generally made convex, or rounded, though threedistinct sides may be formed, thus somewhat increasing theheating-surface, but in other respects not' so desirable.

The outside of theflne, both at the bottom and back of the reservoir, iscovered by a single plate, 0, of castiron, formed so as to lit and coverthe flue-cavity tightly. It is properly secured to the reservoir, makinga good finish with its surface. Its inner end projects inward, throughthe draught-aperture f, in the back, E, of the stove, and has ahook-shaped or angular downward projection, c, to hold upon the saidstove-plate, and thus help sustain the reservoir.

The reservoir, except its cover, is, therefore, made of only two piecesofcast iron.

What I claim as my invention, and desire to secure by Letters Patent,is-

A hot-water reservoir, A, having a flue, B, both at the bottom and back,indented throughout its whole extent, into the body of the reservoir,and arranged so as to receive the draught directly through the backplate of the stove, substantially as and for the purpose hereinsp'ecified.

Also, casting the entire reservoir, except the covers, in two partsonly, one part forming the body of the reservoir and the inside of thefines, and the other part, 0, being an angular plate, covering the wholeoutside of the fines, as herein set forth.
